LEOPOLD FUCHS, OF ROSLYN HEIGHTS, NEW YORK.

SUPPORT FOR LOOM HARNESS.

Application filed August 10, 1922. Serial No. 580,938.

To all whom it may concern:

Be it known that I, LEOPOLD FUCHS, a citizen of the United States,residing at Roslyn Heights, in the county of Nassau and State of NewYork, have invented certain new and useful Improvements in Supports forLoom Harness, of which the following is a specification.

The present invention has to do with improvementsin loom apparatus, andin particular to novel supporting means for loom harness, as speciallyadapted for use in conjunction with fancy weaving or jacquard mechanismsin whichthe harness is connected to horizontally operating orreciprocating actuating devices, such as shown in my prior patent forimprovements in jacquard mechanisms for looms, No. 1,214,449, datedJanuary 30,1917.

My invention has for its primary object the provision of means wherebythe harness cords for weaving either wide or narrow ware may be soarranged as to maintain a spaced non-crossing or intersectingrelationship, to thereby eliminate the wear incident to the chafingoccurring in the usual arrangements, and the complicacy of inter lacingof the many cords which requires expert labor in the process ofpreparation for weaving operations. In other words, in the use orapplication of my invention, I am able to dispose the series of cordswhich are operated by any one of a horizontal row of griff bars in suchrelation to those of the next or adjacent row that they will lie inseparate or spaced vertical planes, and to in this manner provide justas many of such vertical series as may be desired within the capacity ofthe harness actuating instrumentalities, without such cords crossing orinterfering with one another.

A further object in view is to provide for the arrangement of theharness cords into distinct groups, as when weaving a plurality offabrics, and the adjustment of any one group as a unit with relation toanother group to best position the individual harness cords to accordwith the width of the fabrics to be woven.

A still further object in view is to provide means for raising orlowering the harness cords, for varying the spacing between the cordswith respect to their vertical series, and to adjust the verticaloperating portions of the cords with relation to the batten of the loom.

My invention embodies further novel means cooperative with the harnesscords whereby groups of the same may be shifted one' with respect to theother, depending upon the width of the material which is to be woven, soas to best fix in relation to the prescribed spaces of the batten.

These and such other objects as may hereinafter appear are .attained bythe novel construction, combination and arrangement of parts to behereinafter specifically described and claimed.

Reference will now be had to the accompanying drawings forming a part ofthis specification, wherein:

Figure 1 is a view in end elevation of my particular improvementsapplies to a. Jacquard loom, such as when weaving a plurality offabrics.

Figure 2 is a vertical sectional view showing one of the supportingframes for the harness cords in elevation, a portion of the spacingwires or members for the respective harness cords being omitted.

Figure 3 is a vertical sectional view through one of the supportingframes.

Figure 4 is a sectional view taken about on the plane indicated by theline 4:4.- of Figure 3.

Figure 5 is a perspective view of a novel compass board used with myinvention.

Figure 6 is a detail view of one of the removable spacing bars employedin the compass board.

Throughout the following detailed description, and on the severalfigures of the drawing, similar parts are referred to by like referencecharacters.

Referring to the drawings, A designates the loom frame which preferablyincludes their position transversely arranged bars or I-beams B,

upon which the main feature of my apparatus is supported, as will behereinafter described. Projecting laterally from the frame A of the loomare the supports C upon which the supporting frame D for the griff barsis mounted, such mechanism being clearly disclosed in my prior patentabove mentioned. In the sup ort D are positioned in horizontal rows aplhrality of griif bars E, terminating in hooks with which the harnesscords Fare connected. These respective grifl' bars are actuated by meansof horizontally reciprocating griff frames G, so as to give rising andfalling movement to the warp threads of a fabric. It is unnecessary todescribe this type of jacquard mechanism, which is well known in theart, it being suflicientto indicate that the positioning of the harnessactuating members horizontally necessitates provision bein made tochange the direction of motion 0% the harness cords from the horizontalplanes to vertical planes, as is disclosed in my prior patent of whichthe presentvmechanism is an improvement. Mounted upon the cross pieces Bof the loom frame A are, in the adaptation illustrated, a series ofsupporting frames 1 over which the harness cords pass, so that theseharness cords will have vertically disposed portions lying over the warpthreads. One of these frames only will be specifically described.

' The supporting means for the harness comprises a pair of clampingbrackets 2 adjustably mounted upon the loom frame through theinstrumentality of the clamping screws 3. The supporting frame comprisesthe U- shaped holder 4 pivotally connected to the clamping brackets 2 bymeans of the pivot bolts 5. The side membersof the holder 4 are channelshaped so as to slidingly receive the rectangular frame '6 carrying aplurality of spaced rods 7 of glass or the like, there being one of suchrods for each horizontal row of grifi' bars E of the jacquard mechanism.It will thus-be seen that the harness cords of the lowermost row ofgrifi' bars, indicated by the reference character a, will pass over thelowermost rod 7, changing their direction from the horizontal to thevertical, such vertical portion depending to a point adjacent the warpthreads. Each of these harness cords of the row is connected to itsproper coupling cord and mail through which the warp thread passes. Thenext higher row of harness cords b of the horizontal row of grifi barspass over the second rod 7 of the frame and depend in close proximity tothe harness cords a of the first row mentioned. Without referring to theadditional harness cords, the same arrangement applies to the variousother series of harness cords 0, (1, etc. Within the frame 6 are mounteda series of vertical wires or spacing rods 8 held in their spacedrelation by means of the apertured reeds or holding bars 9, therepreferably being employed one of such bars at the top, one at thebottom, and one centrally of the frame, and these bars hold the harnesscords of the respective rows separated orspaced' properly apart.

Referring to the mounting of the frame 6, it will be observedparticularly by reference to Figure 2 of the drawings that the saidsliding frame is held at adjusted position by means of the adjustingscrews 10 carried by the bottom member of the holder 4: and by means ofthese screws the frame 6 may be raised or lowered in its holder'for thepurposes hereinafter specifically pointed out.

drawings, consisting of theside bars 11 which are connected to thejacquard support D by=means of the fastening members 12. Each bar issustained by the necessary intermediate supporting standards 13 carriedby the loom frame. Upon such side bars are mounted at each side of aframe 1 a pair of clamps 14, adapted to engage with the frame and holdit in its fixed position It will be apparent from the foregoing that awide range of adjustment of the harness is permitted by virtue of thearrangement hereinbefore described and now to be further set forth. Inthe first place, the support D for the grifi' bars is shiftably mountedupon the support C and held in any desired position by means of theclamping screws 16, and a stop screw 17 is secured to the loom frame ateach side of the support D so as to hold this member at its fixedposition. Obviously, movement of the support D toward the left willcause the harness cords to be raised and movement of this support D inthe opposite direction will ef fect lowering of the harness cords,speaking with reference to the vertical portions of the cords in eachinstance. Furthermore, swinging of the frames 1 about their respectivepivots 5 will likewise cause the harness cords to be raised or lowered,but more particularly this swinging adjustment of the frames is designedto control the position of the series of cords a withrespect to the nextseries I), and so forth, so that when it is desired to bring theseseries of cords into closer relation the frames 1 will be swung towardthe jacquard, as when weaving narrow ware, while the swinging of theframe 1 in the opposite direction away from the jacquard will modify theposition of the series of cords to increase the space between the same.The vertical adjustment or the sliding of the frame section 6 upwardlyor downwardly will obviously lift or lower the harness cords, and thesevarious adjustments are provided in order that the disposition of theharness cords' may be regulated both with respect to each other and withrespect to the spaces in the batten H through which the warp threadspass. All of the cords in the row a are held in their regular spacedorder, separate and distinct from the cords making up the series 7), andso forth, and the cords which depend from any one frame are capable ofbeing adjusted as a unit by the movements or adjustment of thatparticular frame. All of the frames may be simultaneously adjusted bythe bars 11.

Hence it follows that any framed roup of cords X may be adjusted with reation to another framed group of cords X as may be desired, to accordwith the spaces in the batten, or to accord with the width of the fabricwhich is woven. If the fabric is wide the frames 1 are adjusted closelytogether, Whereas if a plurality of fabrics are being Woven by the loommechanism the frames 1 are separated into the position as shown inFigure 1. In order to maintain the harness cords in grou ed relationwith respect to the individual fa rics, I preferably employ, inconjunction with the supporting frames 1, compass'boards 18 constructedas shown in Figure 5 of the drawings. These frames are composed of thelongitudinally arranged rods 19, 19', and transversely arranged rods 20,each of which is removably mounted in its position to produce the properindex to accord with the weaving. The side member 21 of the compassboard is formed with a flange 22 engaging about the I-beam J, whi e theopposite side member of the compass board, indicated 23, is providedwith a clamping or set screw 24 engageable with the conti ous I-beam Jfor securing the compass l idard in its proper position. By employingthe compass boards in this manner all the cords of a group X aremaintained in close relation so as to fall directly vertically from thisboard to the warp threads, and said frames are individually adjustableas may be desired. The complicacy of interlacing of-harness cords isgreatly simplified by such an arrangement, so much so that unskilledlabor may be employed for the purpose of preparing the looms foroperation, and the ,removability of the bars 19, 19, and 20 makes itpossible to modify the index at will without dislqonnecting the harnesscords from the ac s.

It will be observed in the drawings that the vertical sections of theharness cords are attached to the horizontal sections at points adjacentto the frames 1, and in reference thereto I desire it to be understoodthat this arrangement may be modified as desired. Other changes in thespecific details of construction of the a paratus may be made withoutdeparting 0111 the spirit of the invention and within the scope of theclaims hereto attached.
